ABSTRACT:
A fluid line coupling apparatus comprising a first enclosure and a second enclosure. The first enclosure has a first passageway extending therethrough and a piston slidably disposed therein. The piston is movable between a closed position, wherein the first passageway is blocked by the piston, and an open position, wherein the first passageway is not blocked by the piston. The second enclosure has a second passageway extending therethrough and a collar slidably disposed therein. The collar is movable between the closed position, wherein the second passageway is blocked by the collar, and the open position, wherein the second passageway is not blocked by the collar. The first and second enclosures are engageable such that the front surface of the piston and the front surface of the collar lie in a substantially common plane when the piston and the collar are in their closed position.
